JOHN A. WEIMER, OF LEBANON, PENNSYLVANIA.

BOGlE-TRUCK FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 717,060, dated December30, 1902.

Application filed September 4, 1902.

To all whom it may concern:

Be it known that I, JOHN A. WEIMER, a citizen of the United States,residing at Lebanon, in the county of Lebanon and State of Pennsylvania,have invented certain new and useful Improvements in Bogie Trucks forRailway-Oars; and I do hereby declare the following to be a full,clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to railway-cars,and has especial reference tobogie-trucks used in connection therewith on cinder-cars, hot- Inetalcars, and cars used for other purposes; and it consists in certainimprovements in construction, which will be fully disclosed in thefollowing specification and claims.

In the accompanying drawings, which form part of this specification,Figure 1 represents a side elevation of a bogie-truck provided with myimprovements; Fig. 2, a front elevation of a section thereof, thecoupling being omitted; Fig. 3, a top plan view of the same; Fig. 4, afront elevation of the bolster, partly in section and on a reducedscale; Fig. 5, a vertical transverse section of the same Fig. 6, a topplan view of the cross or transom member; Fig. 7, a front elevationthereof; Fig. 7, an end view ofthe same; ,Fig. 8, a top plan and avertical transverse section of the bearing-plate detached, and Fig. 9 abroken vertical longitudinal section of the bolster and the cross ortransom member.

Reference being had to the drawings and the designating charactersthereon, 1 1 indicate the side or lateral members of the truck,connected together by the cross or transom member 2 thereof, said partsbeing preferably of cast-steel. Said lateral members, unlike theiranswering or corresponding parts as heretofore constructed, are so made,preferably, as shown particularly in Figs. 1 and 3, that the wheels ortheir axial centers are adapted to be brought comparatively closetogether to more readily accommodate the travel of the latter inrounding sharp curves in the track. This is provided for mainly by thearrangement and construction of the cross or transom member 2 and themanner of effecting connection therebetween and said lateral members atpoints in a plane above said Wheels and within prescribed limits, aswill be presently explained. Said lateral members are suitably made toreceive the journal boxes or bearings of the wheel-axles and the usualsprings or cushions for said journals, preferably as shown. Said lateralmembers are, however, widened centrally, as at 11, at their upperlaterally-extended edges or surfaces for a purpose later described. Saidcross or transom member, preferably cen trally downwardly-curved in itsupper surface, as disclosed particularly in Figs. 7 and 9,is rectangularin its general outline in plan, with narrow arcuate portions orelevations 22 short distances inwardly from its ends and projectingsomewhat beyond'boththe forward and rear edges of the upper surface ofsaid transom member after the fashion of arcs of a fifth-wheel of avehicle, the object of which will appear presently. Beyond saidelevations or arcuate portions 22 said transom member is provided withplate-like extensions 4 4, having themselves downwardlyextending orpendent projections or flanges 44. The straight or vertical end walls orsurfaces 5 of said transom member engage or fit against the inner sidesof the lateral members 1 1, while the plate-like lateral portions orextensions 4 overlie or rest upon the top widened portions 11 of saidlateral members, and the pendent portions or flanges 44 fit against theouter edges or surfaces of said widened portions. Said plate-likeextensions are provided with,preferably, rows of holes 6,through whichare inserted bolts 7, passing through registering holes produced in thewidened portions 11 of said lateral members and nutted thereunder,effecting the securing together of said parts, as shown. Through holesalso produced in the lower end portions or surfaces 5 of said transommember areinserted securingbolts 8 8, passing through said lateralmembers, additionally fastening said parts together. Said transom member2 below its upper rectangular surface is preferably of the constructionshown, having a vertical web 33, lozenge or double-Y shaped, as shown indotted lines in Fig. 6, with the widened separated portion centralthereof and tapering or converging from the longitudinal center of thetransom to and integral with the vertical lower end portions 5, securingstrength combined with lightness. Said transom member by reason of itsconstruction reduces the number of fastening-bolts to the minimum, andyet is strongly and firmly held in place to the lateral members. Alsothe converging or tapering of the web of said transom member toward itslower end securing portions 5 provides, in connection with the overlyingend securing plates 4, for arranging the carwheels comparatively closetogether, as above noted and for the purpose aforesaid. Also bolted orriveted centrally to the upper surface of said transom member 2 is anannularly-grooved circular plate or table 10, and above said member orpart is arranged or disposed the bolster 12, having annular pendent ribsor rings 13 at its center upon the lower surface engaging, as shown, thecorrespondingly-grooved surface of said table or plate. Said bolster isheld re'volublyin such position by a king-bolt 14, passing therethroughand through said transom member, it being suitably headed in adepression or enlargement of the opening in saidmember receiving it andheld at its lower end by a pin inserted transversely through said, boltbelow said member. Said bolster may also be equipped with a preferablyremovable rack 15, as in employing the truck or invention in connectionwith a car of the type or class for conveying molten or liquid cin der.Although herein shown and described as applied to this particular classof cars, said truck is equally adapted for use, as is apparent, with anycharacter of car, as above noted. Extending forwardly from and form'-ing, preferably, a common casting with said bolster is a sleeve orpocket 16, adapted to suitably receive and permit of the propercushioning therein of the draw bar or head 17 for connecting or couplingthe truck to any suitable means or motor for its ovement, as may berequired. Suitable manipulating means or lever arrangement 18,supported, preferably, as shown or otherwise, may be employed foradjusting or disposing said coupling in operatively Connecting up thesame with the motor. A casting or crossbar 19, fastened or bolted to,and connecting together, the lateral or side members 1 1 near theirforward ends, also serves to support the forwardly-extending draw bar orhead 16 with its coupling, as greatly desired for that purpose torelieve the preponderant weight of said parts, being otherwiseunsupported beyond the bolster. Said cross-bar or casting is suitablycurved upwardly from under the draw-bar 16 toward or atits end portions,as shown particularly in Fig. 2, and secured or bolted, as at 20, to thetop surfaces of the lateral members near their forward ends, as alsoseenin said figure and Fig. 3. Said support or cross-bar 19 has cast orintegral with its upper surface strengthening rib-like portions orelevations 21, preferably extending from points upon each side of andshort distances away from its center and clear to the ends of saidcross-bar, said bar being preferably rectangular in its general contourand rectilinear or fiat, especially where it forms a support or rest forthe draw bar or head, as seen in Fig. 2.

In the organization or carrying into effect my invention I employ onlythree castings and, as before intimated, reduce the number of bolts forconnecting the parts together.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. In a car or bogie truck, the combination of side members, a cross ortransom member connecting the side members and having end or lateralsecuring extensions in the plane of said transom member, and providedwith vertical end members, said extensions overlying and engaging theupper edge orsurface of said side members, and said vertical membersengaging one side of said side members.

2. In a car or bogie truck, the combination of side members having uppercentral widened portions, a transom member having end or lateralsecuring extensions and pendent terminals, and vertical end members, andmeans for fastening said lateral securing extensions to said widenedportions, and said end members to one side of said side "members.

3. In a car or bogie truck, side members, in combination with a transommember connecting the side members and having end or lateral securingextensions provided with downwardly-extending terminals, the formeroverlying the upper surfaces of said side members, and the latterengaging said members laterally, and said transom member also havingvertical end securing portions inward from said extensions.

4. In a car or bogie truck, side members, in combination with a transommember connecting the side members and having end or lateral securingextensions provided with downwardly-extending terminals, the formeroverlying the upper surfaces of said side members, and the latterengaging said members laterally, said transom member also havingvertical end-securing portions engaging said side members, and a bolsterrevolubly mounted upon said transom member and bearing upon arc-shapedelevations on the last-named member.

5. In a car or bogie truck, side members, in

combination with a transom member provided with lateral securingextensions, and vertical end members, and a vertical web separatedlaterally in the center, converging toward each end and connected tosaid end members.

6. In a car or bogie truck, a transom member having acentrally-depressed upper portion or surface, a bolster adapted'to restin the depression and revolubly mounted upon said surface, said bolsterhaving a forwardlyextending integral pocket or sleeve adapted to receivea coupling.

7 In a car or bogie truck, side members, in combination with a transommember con- IIO or sleeve, and a cross-bar connected to said sidemembers near their forward ends, and having a central depressed portionarranged under said pocket or sleeve, and upwardlycurved ribstrengthenedend portions secured or bolted to said side members.

In testimony whereof I affix my signature in presence of two witnesses.I
